Fueling Stations vs. Monster Rocket, Dana Rohrabacher, Space News
"At the end of our July 12 House Science, Space, and Technology Committee hearing, "A Review of NASA's Space Launch System," I asked NASA Administrator Charles Bolden about the relative cost of using the technology of on-orbit propellant depots instead of relying on new large heavy-lift launch vehicles. He replied that he believed the studies had been done, and the fuel depot solution proved to be more expensive, and promised to get me the full answer. As of this writing, I am still waiting for that answer. It has been more than three months, and NASA has not provided any analysis, or any data at all, that shows why depots are not a good solution or why they are more expensive."
